To aZZ-whom itmay concern:

-Be..it lmown that LH'AR'RY R. OoFF Y, a citizen of the United States, residingat Chi cago, in the county 'of Cookand State .ofIllinois, have lnvented certain new and useful I Improvements in'Electric -LightSwitches, of

which the following is a specification.

.The object of my invention is toprovide mean's for obviating the difliculty in turning the switches of overhead lights, which are frequently placed so high as to be out of' reach. f

I have devised' -*means whereby chains,'cordsor' other pendpendent members are of cut members can be attached to the usual handle of an electric light fswitch. The suchlengthas to ang within easy reach and. the switph can be closed or 0 ened by pulling upon one oi; the other of said members. 1'

In the drawing-Figure 1 is a view of an incandescent lamp with my invention applied thereto; Fig. 2 isa .perspectiveview; of the attachment separated from the lamp; and Fig. 3 is a fragmentary View of a part of the attachment. I Y

I have shown my invention in connection with .an incandescent lamp socket of com mon construct-ion. In those cases'where the socket is turned so that the handle a of the switch'is on the lower side, it will be found advantageous to turn the socket to thepo sition shown in Fig. 1 of the drawing, in which figure the handle is shown projectin at the side of the socket.

generally in use may be turnedb sim ly oosening the usual set screw Whic holdb it in place. 1 The form of myinvention shown in the drawing comprises a strip of metal n, prefer ably of brass, bent to the form shown In 2. In this figure I have shown the metal .strip bent to conform to theshape ofthe usual handle a of the light switch andformed with outward] extending lips 0,0. The lips o, o are provi ed with a ertures for the reception of a screw threaded ever member p. The aperture inthe lip 0 1s screw threaded; In unching the hole in the lip o sufficient meta will be outwardly deflected Thefform o as {shown at g1 toaflord" space for several screw threads, evenwhen the metal operated upon is comparatively thini 1 The screw p is a a shoulder r designed to abut formed with against the'ear. o, the aperture in which is not provided withascrew thread."

f It will be obvious that this construction ,afior'ds means for securely drawing the clam ing member n in place upon the switch han e aby tightening the screw p. The

toinsure a more secure hold upon the switch handle a. In ;the nesent instance I have shown inwardly de ected points m formed 'by slitting and striking inwardly a pormember is formed. ever, that other meansmight be adopted for the same purpose. Chains or other pendent members are attached to the ends of the screw p, which is made. of sufiicient length to afford the necessary leverage for turning endentmembers. In the present instance have shown apertures in the ends of'the screw and rings insertedtherein to which the pendent members are attached.-- While I have shown these endent members in the -form of chains,it be obvious that cords or ribbons might be substituted therefor. At the lower ends of the chains I have shown the hand. 1 It will be obvious that the switch may be moved from the closed to the open position, or Vice'versa, by'pulling upon the proper chain. a

While I have described one specific form of my invention, my invention is not limited to that s ecific form, but covers the features Y set forth 1n the following claims.

What I claim is- Y com rising a clamping member formed to fit t e switch handle, said clamping member having. outward! .extendin member mounte in said IPS, said lever member having means co-operating with the lips for adjusting the clamping members on gs 7c, l toafford a more" eflicient hold for 1.
